Practice Guideline: Idiopathic normal pressure hydrocephalus: Response to shunting and predictors of response: Report of the Guideline Development, Dissemination, and Implementation Subcommittee of the American Academy of Neurology

In the Practice Guideline “Idiopathic normal pressure hydrocephalus: Response to shunting and predictors of response” by J.J. Halperin et al. (Neurology 2015;85:2063–2071), there is an error in figure 1. The R_o value on the x-axis and in the sixth line of the figure legend should read >12, rather than ≥12 and <12, respectively, as originally published. The authors regret the error.
